What free SPYWARE program should I get?

I know there are a few, i'm not sure which ones to trust. What do you all have, and what could you recommend for me to use? I currently have 'Ad-Aware', but I know there are others and want to try them out.

Use both. Not any one program gets it all! The both seem to have regular updates, just make sure you are running the current version. Also visit trend.com and run their spyware a/v routine on your puter. I'm also using Avast a/v program free and it auto updates!

I'm asked this question (the original topic question) so often at work, that I wrote up something that gathers together my thoughts on it and links to the software I recommend. Now, whenever someone asks, I just send them the link to my site.

I approach this from the angle that software should be free, so there may be better stuff out there. But, I really doubt it.

Oh , and what is a virus and what is spyware? We don't got those things in Mac land, must be because Macs suck eh?

We don't get them in Mac land... YET. We (Mac users) have just not yet drawn the ire of the hackers and programmers who write the spyware. As soon as we achieve a larger share of the software market, we'll be a target. Any Mac user who does not use anti-virus software is just asking for it. It's all a matter of time.
